    Undergrad Finding n for Line Spectra with 400 nm Wavelength

    I was given 400 nm. I was tasked to find n but i kept getting a value which is a not a integer. The value of n must be an integer right? 1/W = R(1/4 - 1/n^2) manipulate n=sqrt(4RW/RW-4) where R=1.097e7 n=6.752 I am thinking to make n as 6. But are there values of n greater than 5?
